Abstract
An apparatus for generating light having a plurality of wavelengths comprises a housing (1) and light sources (2) inside the housing (1). The light sources (2) are especially in the form of laser diodes. Preferably, three light sources having different wavelengths are formed. The apparatus further comprises collimating lenses (3) for collimating a light beam emitted by the light sources (2), and beam guiding elements for bundling the light beams. The collimating lenses (3) are disposed in a positioning module (4) that allows the collimating lenses (3) to be placed in different positions during the manufacturing process of the apparatus.
